How to Catechumen Horsepower to Watts

To convert horsepower to a watt measurement, apply one of the formulas below.

Mechanical Horsepower to Watts

Formula to convert mechanical horsepower to watts:

watts = hp(I) × 745.699872

Since one mechanical horsepower is equal to 745.699872 watts, the formula to find watts is to multiply mechanical horsepower by 745.699872.

For instance, here'southward how to convert 5 mechanical horsepower to watts using the formula.

v hp(I) = (five × 745.699872) = 3,728.499358 Due west

Electrical Horsepower to Watts

Formula to convert electrical horsepower to watts:

watts = hp(E) × 746

Since one electric horsepower is equal to 746 watts, the formula to detect watts is to multiply electric horsepower by 746.

For case, here's how to convert v electric horsepower to watts using the formula.

5 hp(Due east) = (5 × 746) = 3,730 Westward

Metric Horsepower to Watts

Formula to catechumen metric horsepower to watts:

watts = hp(M) × 735.49875

Since one metric horsepower is equal to 735.49875 watts, the formula to find watts is to multiply metric horsepower past 735.49875.

For instance, here'due south how to convert 5 metric horsepower to watts using the formula.

5 hp(Grand) = (5 × 735.49875) = 3,677.49375 W

Boiler Horsepower to Watts

Formula to convert boiler horsepower to watts:

watts = hp(S) × 9,809.v

Since one banality horsepower is equal to 9,809.5 watts, the formula to find watts is to multiply boiler horsepower by 9,809.five.

For example, hither'south how to convert 5 boiler horsepower to watts using the formula.

v hp(S) = (five × ix,809.5) = 49,047.5 West

Horsepower and watts are both units used to mensurate ability. Keep reading to learn more about each unit of measure.

Horsepower

The term horsepower was adopted by Scottish inventor James Watt to measure out the ability output of his steam engine and to compare that power with that of horses horses.[1] Horsepower were later used to measure the power output of piston and turbine engines and electrical motors.

At that place are at present several unlike types of horsepower, including mechanical, electric, metric, boiler, restriction, and indicated, and they all have different applications in industry. Mechanical and electrical are the most normally used types.

Mechanical Horsepower

Mechanical horsepower is often used to measure the output of engines and motors in North America. 1 mechanical horsepower is equal to 745.69987158227022 watts.

The mechanical horsepower is a US customary and imperial unit of measurement of power. Mechanical horsepower can be abbreviated as hp(I); for example, one mechanical horsepower can be written every bit 1 hp(I).

Electric Horsepower

Electric horsepower is used to measure out the output of electric motors and other electric machines in the US. One electric horsepower is equal to exactly 746 watts.

The electric horsepower is a United states customary and regal unit of ability. Electric horsepower tin can be abbreviated as hp(East); for example, 1 electrical horsepower tin can be written as 1 hp(Due east).

Metric Horsepower

Ane metric horsepower is the power needed to one metric horsepower as the lift a 75 kilogram mass at at one meter per second.[two] One metric horsepower is equal to 735.49875 watts.

The metric horsepower is a non-SI metric unit for power. Metric horsepower can exist abbreviated as hp(M), and are as well sometimes abbreviated equally PS, cv, hk, pk, ks, or ch. For case, ane metric horsepower can be written equally 1 hp(M), one PS, 1 cv, 1 hk, ane pk, 1 ks, or 1 ch.

Boiler Horsepower

Banality horsepower is used to measure the ability of a boiler to generate steam. One boiler horsepower is equal to the power needed to evaporate 34.v pounds in one hr.[3]

Banality horsepower tin can be abbreviated every bit hp(Southward); for case, 1 boiler horsepower can exist written equally 1 hp(S).

Endeavour our engine horsepower reckoner to calculate the ability of a motor.

Watts

Ane watt is the power equal to the rate of free energy of one joule per second in an electrical excursion.[4] One watt is also equal to the power produced in a circuit with a voltage potential of one volt with a current of one amp.

The watt is the SI derived unit for power in the metric arrangement. Watts can be abbreviated as Westward; for instance, 1 watt can be written equally one W.

Watt's Police force states the relationship betwixt power, current, and voltage. Using Watt's Police force, it's possible to limited the ability in watts as an expression using current and voltage.

PW = IA × VV

The power in watts is equal to the current in amperes times the potential difference in volts.

Combining this with Ohm'due south Law, information technology'south besides possible to express the ability in watts using resistance in addition to volts and amps.
